Introducing...
pV/T Master ™ - Volumetric lab in-one
The pV/T Master™ is a novel and versatile volumetric analyzer that allows implementation of variety of static and dynamic techniques by using the core instrument and optional or user provided ancillary hardware. As presented, the basic instrument can be used for volume (density) measurements of any solid state samples and compressibility studies of cellular materials (foams) using gas expansion technique or time domain pycnometry. The open-architecture design allows for using all resources for variety of research activities.

Possible extensions:
- Non-isothermal measurements using external sample chambers at different temperatures - Easy extension of the sample volume range well over 100 mL - Bubble point technique - Liquid expulsion porometry - Gas transfer rates through various barriers, like films, filters - Flow rates measurements through packed beds of powders - Surface area analyzers, e.g. by flow through packed beds of powder – permeability technique or physical sorption using cryogenic temperatures within the transducer pressure range (0 - 340 kPa) |
